As Silent a Protagonist as a Book can Have?

After another 100 pages of Jam, the story has gotten much more interesting.

I have noticed, over these last 100 pages, however, that Croshaw starts to either get lazy or just a little lax and begins to mix in the third person omniscient perspective. It's only a paragraph here and there, but it's noticeable when you come to it, and a little jarring if you stop to think about it. After all, he's got the character of Travis to work with, and that's been enough so far.

Though, it must be said that Travis doesn't seem to have much character or personality. We're only infrequently treated to his deep thoughts and see much more of his actions. Though keeping the Goliath bird eater with him does say something - even more is said by his naming it "Mary."

It also needs to be mentioned that Croshaw's background in/vast experience with video games could be showing through in his main character.

Travis' apparent lack of any colourful or powerful personality might just be a reflection of so many video game heroes that have the minimum allowable personality so that players can relate to them and use them as a proxy in the world of the game. Though, speaking personally, I can also relate to Travis' indecision and tendency to drift from one situation to the next in the same way that most Millennials are likely to be able to.

The plot continues onwards with very little stoppage, and the characters interact in such a way that is, for the most part, natural.

Travis and Don are currently at the Hibatsu building, where they've just been assigned to work as reconnaissance agents for the people there, their job being infiltrating the mall and letting Hibatsu know what's going on over there.

The way that the jam sought out the apple when Travis was wading through it earlier, and how it seemed to ignore him while doing so, along with the note about the jam crawling higher up the Hibatsu building than any other suggests that it doesn't just feed on organic matter, but it's also drawn towards it as it grows or decays (as was the case with the apple). Blocking rooftop gardening as a prospective survival method because of this attraction to growth would throw the story for a real twist, but I'm not going to find out about that for another 100 pages, I'm sure.

Also, X and Y seem to have some sort of agreement with someone, possibly the people at Hibatsu. We'll soon see.
